A vacuum pressure regulator is a device used to control and regulate the pressure within a vacuum system. 

It is an essential component of many vacuum systems, especially those used in scientific research and industrial applications where precise and stable vacuum pressure is critical. 

The vacuum pressure regulator works by controlling the flow of gas into or out of the vacuum chamber to maintain a set pressure level. 

This allows for precise control of the vacuum pressure, which is essential for many applications. Such as semiconductor processing, material science research, and vacuum coating. 

Vacuum pressure regulators come in various designs and configurations. Including manual and automated versions, and can handle a wide range of vacuum pressures, from high vacuum to low vacuum levels.
